(57) Disclosed is a refrigerator. The refrigerator includes a storage space (2) capable
of keeping a low-pressure state; a vacuum pump (3), including a pump body (31) for
defining a pump cavity (30), an air inlet (321, 322) communicating with the pump cavity
(30), an air outlet (331, 332) communicating with the pump cavity (30), a piston (36)
accommodated in the pump cavity (30), and a driving device for driving the piston
(36) to move in the pump cavity (30); and an air exhaust path (4), connected to the
storage space (2) and the air inlet (321, 322). As suggested, the driving device includes
a coil (381, 382), wherein the coil is capable of generating an electromagnetic force
for driving the piston to move in the pump cavity, so as to suck air in the storage
space into the pump cavity via the air inlet and discharge air out of the pump cavity
via the air outlet.
